ARTHUR THOMAS BALL, OF MOUNT VERNON, NEW YORK.

Specification of Letters Patent. Patented Sept, 26, 1911, Applicationfiled April 5, 1911.

Serial No. 618,989.

Toall whom it may concern:

Be it known that I, ARTHUR T. BALL, a citizen of the United States,residing at Mount Vernon, Westchester county, State of New York, haveinvented certain new and useful Improvements in Pin-Guards, of which thefollowing is a full, clear, and exact description.

My invention relates to what I will term a pin-guard, the same being auseful appliance to be employed in connection with any sort of pin,guarded for any purpose.

In the drawings I have shown my invention as applied to a hat pin andalso to a scarf pin. In the former event, it protects the point of thepin and in the latter event, it prevents danger of loss.

The invention consists primarily in the novel construction of the guard,which, as shown, is of the greatest possible simplicity.

In the drawings, Figure l is a side elevation of a hat pin having aguard applied thereto, constructed to embody my invention. Fig. 2 is alongitudinal section of the pin-guard proper, showing a pin in place.Fig. 3 is a plan view of the parts as shown in Fig. 2, the outer sleevebeing shown in section. Fig. 4L is a cross-section of the parts shown inFig. 2, said section being taken at the middle of the guard. Fig. 5 is asimilar section of a modification. Figs. 6, 7 and 8 illustrate details.

The guard proper is constructed to slide upon a pin and frictionallygrasp the same. It comprises only three parts, an inner tube l, an outertube 2, and a spring 3. The inner tube is cut away on one side andlongitudinally, as shown in Fig. 7 to provide room for a spring 3. Thespring 3 is bowed downwardly so that its intermediate portion willproject into the bore of the inner tube. The ends of the cut-awayportion of the inner tube afford seats for the two ends of the spring 3.When the spring is in place in the cut-away portion of the inner tube 1,the outer tube is slid over the parts as shown in Fig. 2 so as to coverthe spring and spring opening and so as to hold the spring 3 permanentlyin place.

As shown in Fig. 4, the under side of the spring 3 may be flat, or, asshown in Fig. 5, the under side thereof may be channeled longitudinallyto engage a pin throughout a greater area. By preference, one of thetubes, for example, the inner one, is made somewhat longer than theouter tube 2 so that when the parts are assembled, the ends of thelonger tube may be offset to prevent the longitudinal separation of saidtubes when once assembled. It is preferable to make the inner tubelonger because by so doing the ends may be spun outwardly, therebygiving a rounded, or somewhat bellmouthed, pin entrance to the guard.

In Fig. 2 I have shown the guard as it appears in use. In this form theguard is suitable for a scarf-pin. In other instances the guard may havean ornamental covering or attachment, such as 4, of any desired designappropriate as a hat-pin head, the guard proper boing secured to theornamental covering 4 in any desired manner, as by solder.

Vhat I claim is:

A pin-guard comprising two tubes, one iitting within the other, saidinner tube having a longitudinal slot formed in one side thereof, abowed spring located within said slot, supported at each end by andbetween said tubes, the intermediate portion of said spring projectinginto the bore of the inner tube, and means for holding said tubesagainst longitudinal separation.
